Ok so finally had some time to install my Passport 8500 x50 in my 135i Convertible and hardwire it to the fuse box. Set a few hours to do the install.. It took me longer since I soldered all my connections and used heat shrink for all the connections for a nice clean look..even though you cant see them :biggrin:..
1. Start pulling the pillar trim off. I started from the top and worked towards the dash, there are 2 snap-in 9in blue and towards the dash its a slot and hook type where it slides in. Just take your time and be careful.
Here is another pic with it removed. There are 2 snap-in (in blue) and there is groove and hook type towards the dash.
2. Then I started prying out the light assembly above the rear view mirror. There are hooks on all 4 sides. Start from the front, back right, and left. once its loose you can push in the 2 hooks on the right side and it should flip down. (again just take your time not to scratch anything.. If you have trim removal tool, that will really be handy. I didnt so I found some firm but soft plastic tool that worked for me.
3. Next I removed the passanger visor to make it easier to feed the wire. Remove the 2 screws and there should be a cable for the light switch. Very thin wire so be careful and unplug the connector.
4. Next I started running the cable from the winshield towards across the top, down the pillar and to the fuse box.
For the cable I used some left over stuff I had lying around that was rated for 300volts. it was overkill.. but didnt cost me anything :wink:. I then crimped a RJ-11 connector. Then use the heat shrink to make a nice clean look.
Here is the cable going down the pillar headding towards the fuse box.
Here is the cable now by the glove box. I found that it was easier to just follow the directions in the manual to access the fuse box to save some time instead of removing the entire glove box.
5. I then attached the ground to the bolt on the left and used the add a fuse for the power. I used fuse 8.
Here it is installed.
Another Pic from the bottom. I ran the cable around the window sensor for a nice clean look.
When the cord is not in use.. I tuck it around the window senor and wraps around.
Hope this was helpful and enjoy....
